CHARGING BY RUBBING
- When we rub two objects with each other they get charged due to a transfer of electrons between them.
- For example, if we rub a rubber balloon with animal fur, the balloon is made up of rubber that attracts the electrons from the animal fur.
- This results in rubber having an excess of electrons while fur having a shortage of electrons.
- In the same way, if we rub a plastic comb with dry hair the comb acquires some charge.
- When a Plastic comb is rubbed with dry hair it gets charged these objects are called charged objects.
- When two objects are rubbed with each other, electrons get transferred from one object to another
- The transfer of charges is responsible for static electricity in various objects.
- Static electricity is the main reason for lightning
